Model 5415 was conceived as a preliminary design for a Navy surface combatant ca. 1980.   The hull geometry includes both a sonar dome and transom stern.  Propulsion is provided through twin open-water propellers driven by shafts supported by struts.

There is a large EFD database for Model 5415 due to a current international collaborative study on EFD/CFD and uncertainty assessment between Iowa Institute of Hydraulic Research (IIHR), Istituto Nazionale per Studi ed Esperienze di Architettura Navale (INSEAN), and the Naval Surface Warfare Center, Carderock Division (NSWC, formerly DTMB).   The validation data includes boundary layer and wake, longitudinal wave cuts, bow and transom wave fields, and wave breaking.   Links and references to available documentaion can be found at the bottom of this page.  No full-scale data and/or ship exist.
